ARMY TM 92815-256-24 AIR FORCE TO 38G1-96-2 MARINE CORPS TM 2815-24/5 c. Set  multimeter  for  ohms  and  check  rectifier  bridge  assembly  (refer  to  FIGURE  3-10)  by  noting  multimeter indications between point A and each point C, and between point B and each point C.  Reverse leads, repeat checks, and note indications.  If readings are the same in both directions for any diode, replace entire rectifier bridge assembly.  A good diode will have a high indication in one direction and a low indication in the other. FIGURE 3-10.  Testing Rectifier Bridge d. Set multimeter for ohms and check stator (refer to FIGURE 3-11) for open circuits between point D (lamination) and each terminal A, B, and C.  If continuity is noted between lamination and any terminal, stator is defective and must be replaced. e. Set multimeter for ohms and check stator windings (refer to FIGURE 3-11) for continuity between terminals A-B, A-C, and B-C.  If open, replace stator. f. Set  multimeter  for  ohms  and  check  rotor  assembly  (refer  to  FIGURE  3-12)  for  12.0  to  13.0  ohms  indication between slip rings.  Also check that open circuits are indicated between pole fingers and each slip ring.  Replace entire rotor assembly if indications are other than stated. 3-11.6.  Assembly. a. Using press, install front bearing (32, FIGURE 3-6) in front housing (30). 3-32
